".2mL PCR tubes"

Mounted on a wooden stand with a scale, the apparatus is comprised of a three-limbed glass tube with rubber tubing on the center.

Compares thermal expansion of various liquids.

With the magnet is on the outside, it's easy to see the science behind these eddy tubes.

Great density set for physics classrooms and lessons.

Wide range of cubes for density experiments.
